<![CDATA[PASTE/TEXT YOUR ABSTRAX TEXT HEREThe looming threat of a Megathrust earthquake and tsunami along the southern coast of Java compromises not only human safety but also the operational readiness of regional defense and national security. While existing literature predominantly focuses on outbound evacuation flows, there is a critical gap in assessing the resilience of inbound logistics supply chains essential for emergency response operations. This study aims to identify strategic road segments qualifying as National Vital Objects and to delineate isolated territories necessitating Military Operations Other Than War (MOOTW). By employing a spatial network science approach, specifically utilizing Betweenness Centrality algorithms and Network Robustness simulations within the Palabuhanratu road network, this research models the systemic breakdown of access under tsunami inundation scenario, by applying a binary failure threshold of flow depth hmax 0.3m. The quantitative analysis identifies "Jalan Lintas Jabar Selatan" as the critical logistics backbone, exhibiting the highest vitality score of 0.19, representing the dominant outlier compared to other arterial corridors in the network. Concurrently, the hazard simulation reveals the formation of tactical isolation clusters in Citarik and Palabuhanratu, where 22.45% of the network nodes experience total access severance (cut-off). These findings underscore the strategic imperative for establishing joint contingency plans that integrate air-bridge and maritime access capabilities to ensure the continuity of national defense logistics during crisis contingencies.]]>
